My little sister constantly gets on my computer, which is fine, except for when she opens itunes. I have songs that are explicit and don't want her to listen to . Is there any way to have itunes require a password when clicked on in the dock, so that itunes would not open without my password. I realize that i could just log out each time or require the password when waking from sleep, but really itunes is the only app i dont want her opening. Thanks guys.
